Time cursor lag in time series view

[kpreid]

Describe the annoyance
I was exploring the time series visualization capabilities, and I noticed that the cursor marking the current time was lagging behind the graphs when dragged. This does not significantly impact usage, but it's a sign that something could be improved in the update/invalidation/repaint logic to make the visualization more stable and efficiently computed.

To Reproduce
Steps to reproduce the behavior:

1. Open a time series view.
2. Click and drag, or rather, shake vigorously.
3. Watch where the graph intersects the cursor.
